I am confused. simpleName is intended as a readable name for the magic 
code. Does the above mean 64-bit images will never have closure bit set 
or that closure bit is always implied for 64b and will be handled by 
squeak64 automatically?

# classic, +closure, +closure+spur

32-bit = squeak, cog (+C), spur (+C+spur objmem)
64-bit = squeak64?, squeak64? (+C?), spur64 (+C+spur objmem)
